- Solutions are used in dyeing as a mordant and as a coagulant for industrial wastes.

Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Iron(III) sulfate article was read about 21,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 50 and blocks with 29: each hit it takes is cut by 12 %.
